JOU RNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 493,665, dated March 21, 1893.

Application filed November 25, 1392. Serial No.- 452.986. (N0 model.)

To all whom it may concern:

Be it known that I, HENRY J. THOMPSON, a citizen of the United States, residing at Springfield, in the county of I-Iampden and State of Massachusetts, have invented new and useful Improvem ents in J on rnal-Boxes for Locomotive-Trucks, of which the following is a specification.

This invention relates to improvements in ournal-bearings for trucks, more especially designed for locomotives.

The object of the invention is to insure in a journal bearing which is of inexpensive and practicable construction, means of unusual efficiency for the lubrication of the bearing.

To this end the invention consists in the construction and combination of parts, all suba pear and be set forth in the claims. 1

Reference is to be had to the accompanying drawings in which these improvements are illustrated and in which,

Figure 1 is aside elevation of a locomotive truck having the present improved journal bearings indicated thereon. Fig. 2 is a vertical section taken centrally through one of the journal bearings on a plane at right angles to the line of the axle. Fig. 3 is a vertical section of the same taken on the plane at right angles to that of Fig. 2, as indicated by the line, 33. In said Fig. 3 the line 2-2 indicates the section line precisely on which the said sectional Fig. 2 is taken.

In the drawings A represents the journal box, or housing, of which one is provided for each bearing, B indicating the car-wheel-axle and O the pedestalof the truck frame for each journal and D represents the equalizing bar. The journal-box, A, has the external, vertical, and parallel edge flanges, a, a, whereby the box is held in proper engagement with the pedestal while it has its slight vertical movement, as usual. The journal-box, A, is of a rectangular form having the sides I), b, and top, (1. The form of the chamber in the upper portion of said box is semi-octagonal, and the side of the box, intermediately of its height, have the inwardly projected ledges,

G represents the brass or journal-bear ing the same having externally, or at its up per side, the usual semi-octagonal form to closely fit in the correspondingly formed upper portion of the said chamber in the journal-box, the under side of this brass having the same semi-circular conformation as the axle for the directbearing support of the box by the axle. The inner side of the brass is, however, provided with one or more recesses, g, g, which are substantially radially extended relative to the center from which the internal arc-surface of the brass is generated, and partially through the thickness of said part, leaving the curved bearing surface to be comprised in a succession of separated ribs; the brass, at its inner lower corners, is, furthermore, recessed, as at g 9 whereby the bearing surface of the brass is less extended around the sides of the axle. The brass, at its ends, has the integral webs or flanges, h, h, the one, h, at one end having its lower edge arranged to rest on the tops of the aforesaid ledges, f,f, near their ends, while the flange, h, at the other end of the brass, has the lower edge portion of its flange lying along outside the ends of the said ledges which latter terminate, as seen in Fig. 3, slightly within the plane of the open end of the box. The brass has in its top a broad, shallow depression, 2', and the journal-box has in its top, also, a somewhat similar depres sion, and one or more ducts, j pass downwardly through the thickness of metal constituting the top of the box whereby communication for oil may be had from the said depression, j, to the one, i, in the top of the brass; and from said latter depression, 2', one or more ducts, 2' extend through the brass to convey oil downwardly into the aforesaid radial recesses, g, g. The inside of the journal-box, at its top, has the groove, 70, while the brass has the transverse rib, m, at its top for engagement in said groove, which engagement, together with the aforesaid flange, h, at the end of the ledges,f,f, prevent endwise displacement of the brass relative to the box. The equalizer bar having its ends in bearing support upon the tops of the journal boxes, as usual, is provided with the recesses, if de sired, as seen at o, for facilitating the entrance of oil into the journal hearing from the top.

H represents an oil receptacle in the bot tom of the journal-box, the same here being shown as removable and supported upon the inwardly projected rests or ledges, 'n, n, of the box, A. This oil-box has its side, p, at one end of the journal-box, with its upper edge lying under the said ledges,f,f, While the end, q, of the oil-box, at the other end of the journal-box, is projected upwardly far enough to lie alongside the adjacent ends of the said ledges, f, f, and by this engagement the oil-box is held against any endwise movement in one direction. which is spring-supported from the bottom of the box and carries one or more rollers, s, which have a yielding and rolling bearing against the axle. This frame is of rectangular form of such dimensions as to fit for free guiding movements within the oil-box, and opposing members of the frame have the downwardly extended spindles, t, t, with which theupper ends of the spiral supporting springs, u, it, have encircling engagements. The oilbox is provided externally with the thickened portion, w, having the horizontal duct, a,

through it which at one end inwardly communicates with the oil-box and at its other end has connected thereto the entrance pipe, y, for oil. The oil, which is supplied within the oil-box, H, is by the rollers, s, s,-which are rotated by and in contact with the axle of the car-wheel,carried to the axle for the lubrication thereof; and thus it is seen that there are provided in each journal-box the automatic lubricating devices at the bottom, as well as the means for effecting, at pleasure, the lubrication at the top of the bearing. The endw-ise movement of the oil-box inwardly in the direction of the length of the axle maybe insured by a collar on the axle, or the hub of the car-wheel, or otherwise.

I claim.-

In a journal-bearing,- the combination with a journal-box having in its top a depression, and one or more duets leading downwardly therefrom, of the brass having the approximately radial recesses extended from its axle-bearing side and having in its top the depression, 2', and the ducts, 2' 2' leading from said depression, 1', to the radial recesses, substantially as and for the purpose set forth.

2. The combination with a journal-box having in its opposite sides theledges, f, f, which at one end terminate within the end of the box, of the brass having at one end the Web or flange, h, lying alongside the ends of the said ledges and said brass having at its top a rib and groove engagement with the internal upper surface of the journal-box, substantially as and for the purpose set forth.
